ing parts eXtendthrough the enclosing. wall housing the valve mechanism,and such parts must" be packed to prevent the escape of Such packings ifthey prevent the escape of water make the parts hardto operate and theyare very liableto' deterioration.

One of the: primary objects of the presen wholly enclosed, and withoperating meoha- 'nism' outside the enclosing wall, the" wall havingflexible portions, in thenature of diaphragms, which are laterallymovable, to enable-operation of the valve'mechanism;

Another object fisthe provision of a' dia:-- phragm operated'flushvalve, whereinthe initial opening of the .flush valve admits the fullwater pressure to the diaphragm to opcrate the same, and whereinauxiliary mecha-- nism is provided externally operatedto'em able; theinlet of initial pressure tounseat the flush valve. Another' object isthe provision of mechanism for draining the diaphragm chamber after theflushing operation to' enable seating of the flush valve,externally-operated, and without direct connection with 'the externaloperatingmechanism. Q Another object is thezprovision insueh ap paratus,of means facilitating inspection and removal of the operating parts.

An'otherobject is the provision ofa rela-' tively simple and relativelyinexpensive ap' paratus capable of operation with the usual tank, or:with a siphon filled tank, and adapted to be arranged within the wallof the: bath-room.

' Flg'. 2"i's an enlarged detail in section of V the flushing mechanism.c i In the-present embodinfentof the inven ,tion, a valve casing l isprovided having an inlet 2 atone side; which is connected by a pipe 3,with a compression tankt, the said tank being adapted to contain" adefinite charge of watch-which during its entrance to the tankcompresses the 'a ir'ih the top-of the tank. f I

The top of the c'asingl is closed by a plug 5 threaded intoan' openingin the top; and the' said plug has a handle6 for convenience-inmanipulatingthe same. lntermediateitsitop and bottom'the casing has apartition 7w pro vided with a port 7 normally closed by avalvei in'theform of a cup 8', having a filling 9 of packing which rests upon theupper-face of the partition 7 a when the valve is in closed position. I

The valve has astem 12, which moves in a bearing 13 supported by the cap5 before mentioned, the cap having arms 14, which are connected withthebearing'. v At its upper end the stem has a longitudinallyextendingslot 15', through which passes a pin 16, the endsof the pin beingentered into openings in'the re: duc'ed portion of the cap which engageswith in the opening of the casing 1.v Thus. the valve and stemareconnected tothe cap with a lost motion connection, the pinlimiting'the movement of the valve.

A spring 17 encircles the stem between the bearing 13 and'the valve89,normally holding the valve to its seat,.and a guide collar 18 isthreaded on to the lower end of the stem below the valve,thecollarfittingl'oosely within the port, and extending belowv thelower end ofthe stem as shown. v

The'lower end of the casing is providedwith a lateral port from whichleads a pipe 19'to the bowl to be flushed. Water is sup plied to thechamber 10 of the casing, and to the tank 4, by means of a pipe 20 froma suitable source of supply, the pipe having a cheer: valve 21interposed therein, to prevent return of water to the source ofsupply.

At its lower end the valve casing 1 is enlargedlaterally to provideacircular head 22, which is concav-o-convex, and arranged with itsconcavity downward. This head forms one wall of a diaphragm chamber, theother wall being formed by ahead 23', which issecured to the head 22 bythreaded stems and wingnuts shown at 24. i

A diaphragm 25 of suitable material is arranged within the chamber, theedges of the diaphragm being clamped between the abutting edges of theheads 22 and 23, and anopening or port 26 is provided between thechamber ll'of the casing and the diaphragm chamber. Normally thediaphragm lies in con-.

cave-convex form on the inner face of the head 23, as shown in Fig. 2,and water is admitted to the chamber beneath the diaphragm when thevalve 8+9 is opened, by means of a passage 27, which extends through thewall of the chamber 11, and through the wall of the head 2.3, a checkvalve 28 being provided v at the inlet end of the passage. Referring toFig. 2, it will be seen that the passage27 extends outwardly anddownwardly, then inwardly anddownwardly, and then vert cally upward, andthat the inlet end is enlarged as shown at 29 for the check valve.

1 It will be apparent from the-description that when the valve 89 beginsto lift, water will fiow through the passage 27, past the 1 the valvewill be lifted through the engagement of the rod 30 with the stem 12.Thus the valve 89 is lifted by thediaphragm, but water must be admittedto the-space below the diaphragm to provide initial lifting'movement ofthe valve before water can enter the passage 27. In order to enable aninitial flow beneath the diaphragm, a passage '33 1S provided leadingfrom the chamber 10 to the portion 34 of a chamber, consisting of thesaid portion and a portion 35 of less diameter, the said chamber beingprovided in an extension from the casing 1.

A valveseat 36 is provided between the portions of the chamber, and avalve 37 simi lar to the valve 8 9 cooperates with the seat,

the valve moving downward to open communication between the parts 34 and35 of the chamber, and moving upward to close the communication. Thelower end of theportion 34 of the chamber is closed by a threadedbearing against the diaphragm.

plug 38, and this plug is recessed on its inner face to receive a spring39which engages the lower end of the valve, actingn ormally to seat thesame. The valve may be unseated by means of a push button 41,slidablymountedin a bearing nipple, 42 in the cap 43 which is threadedonto the upperend of the extension 40. The button bears against adiaphragm' 44clamped between the cap and the end of the extensioinjandthe valve has a stem 45 provided with a head 46 at its upper end,

It will'be apparent from the description that when the button 41 isdepressed, the valve will be opened, enabling water to flow from-thechamber 10, through the passage 33 and the portion 34 of the chamberinto the portion 35. From this portion a passage 47 leads to the passage27.

The operation of this part of the mechanism is as follows. In order toflush the bowl, the button 41 is depressed. This opens the valve 37, andwater flows from the chamber 10 through the passage 33, the chamber.

3435, and thepassage 47,into the lower end of the passage 27 ,liftingthe diaphragm 25.

and openingthe valve 8-9. The opening of the valve 89 opens the passage27, and water may now flow directly from the chamber I '10 into thediaphragm chamber, beneath the diaphragm, andthe closing of the valve 37under the influence of the spring 39 is no longer material to theoperation of supplying water to the space. beneath the diaphragm. Whenthe valve 89 is lifted, the water flows from the tank 4, through thepipe 19, to the bowl, thoroughly flushing the same. The diaphragmchamber, thatis, that portion of the same below'the diaphragm is enabledto drain througha passage 48 into the chamber 11. The rate of the flowthrough the passage 48 is regulated by a needle valve 49, which may beadjusted by a handled screw 50; Theneedle valve is in a nipple 51extending downwardly from the head 22, and the outer-end of the nippleis closed by a cap 52, having a threaded opening through whichthescrew50 extends. r

A diaphragm 53 is clamped between the cap and the end of the nipple. andthe lower end of the needle. valve rests on the diaphragm. By turningthe handled screw 50 in the proper direction, the extent of opening ofthe needle valve may be adjusted. In Fig. 1, the apparatus is shownarranged within the wall of a bathroom,. for instance. so that the tankandthe other mechanism is concealed. In order to enable operationof thepush button 41 outside the wall, a panel opening is provided, normallyclosed by a panel 55. r

A bracket 56 is. secured to the inner face of the panehand an elbowlever composed'of arms 57 and .58 is pivoted to the bracket.

rests upon thepush"button- 4&1; The other arm 58'has an extension 59passing through an opening in the panel, and provided with a 'buttontO.When itisdesired to flush the bowl, the buttoni 60*is pressed. inwardly.This presses the'button' d1 downward, and

initiates the flow of the water b'eneaththo diaphragm V a The opening 26is a vent opening. Itwili be apparent that the tank i might suppliedwith water by means of a siphon, 1f desired, instead of directly throughthe casing 1. VVherethe water contains grit, such as" sand, it 1sadvisable toapply arubber sleeve overftl'ie bearing 31, the sleeveengaging the hearing at; one end, and the rod; 30' at the; other. ThisW111 prevent theentrance of grit intothe di'aphragm chamber, 7 In somecases it Will be ladvis'able to place a spring above.

the'check 28. The entire mechanism is enclosed no part thereof extendingbeyond the casing. 1. and its associated parts. 7 V

The valve 87 is operated throughthe anphragm "44,- so that none of theconnecting parts of the valveextend through the casing. This is truealso of the adjusting mechanism for the needle valve."lVater pressureisre I liedv upon to openthe flush'valve. An observation openingisprovided,-indicated at 60. This is 'closediby a disk 61 of glass.

It will be apparent from the description and drawings, that thedischarge isautomatically held open until the pressure in the tankreaches atmospheriqthat is, until-the tank is entirely'empty; As long asthere is water in-the tank the diaphragm chamber does not drain, and itcommences to drain when the tank is empty. The static head beneath thediaphragm is sufiicient to hold the diaphragm lifted. until'the chamber10 is empty, and the tension of the spring 17 exceeds the pressure belowthe valve,

When the water begins to flow from the compression tanlgthe pressuregradually decreases, and near the-end there is a low pressnre,or aslight partialvacumn- In order to compensate for this, and to insureemptying of the tank, a pipe extends from the top of the compressiontank to-the top of chamber 11; With. this arrangement, the entirecontents ofthe tank are always discharged. The pipe 70 is provided withthe usual check valve 71' toretain the pressure in the tank When it isfilling;
